Maytronics Dolphin 2x2 / C6 3-polige Gleichstrom-Kabelsteckverbindung – 9991277

Maytronics Dolphin 2×2 / C6 3-pin DC cable connector assembly

This is the genuine Maytronics OEM 3-pin DC cable connector assembly (part 9991277) designed to terminate the power cable at the motor entry point of the Dolphin robotic pool cleaner. It forms the critical electrical and watertight interface between the floating cable and the robot’s drive/motor unit, carrying DC power across three poles to keep the cleaner running reliably in the water.

Funktion und Design

The assembly comprises a 3-pole connector plug, sealing gasket, and threaded locking cap that together create a waterproof, secure connection at the robot’s cable socket. The connector is keyed with a locating groove so it can only be seated in the correct orientation, eliminating the risk of mis-insertion. Once the cap is tightened, the gasket compresses to exclude water ingress at the cable entry point.

Kompatible Dolphin-Modelle

This connector assembly is specified for the Maytronics Dolphin 2×2, C6, and C6 Plus robotic pool cleaners. The 3-pin DC configuration is also common across a broad range of Dolphin platforms, but always cross-reference your robot’s parts diagram before ordering to confirm fitment.

When to replace this part

Replace this connector assembly if you notice intermittent loss of power or erratic robot behaviour that clears when the cable connection is wiggled; visible corrosion, cracking, or deformation on the plug body or locking cap; water ingress into the motor socket after a cleaning session; or a connector that no longer locks securely into the robot’s entry socket.

Warum Originalprodukte von Maytronics wichtig sind

Counterfeit or generic connectors frequently use undersized gaskets and sub-grade plastics that fail to maintain a reliable watertight seal under pool conditions. The genuine Maytronics part is manufactured to the exact connector geometry, thread pitch, seal specification, and material grade of the original, ensuring correct fit and protecting the motor from moisture damage. Using an OEM part also preserves any remaining Maytronics warranty on the robot.
